ALFRED SCHMIDT, OF LAKE HOPATCONG, NEW JERSEY.

FUELMIXER.

T 0 all whom it may concern:

Be it known that I, ALFRED SCHMIDT, a citizen of the United States, andresident of Lake Hopatcong, in the county of Sussex and State of NewJersey, have invented certain new and useful Improvements in Fuel-MiXers, of which the following is a specification.

The object of my invention is to provide means for automatically causingthe more perfect breaking up and comminution of liquid fuel, such asgasolene, and mixing the same with air for use as a fuel supply forinternal combustion engines, to the end that the fuel mixture will bemore homogeneous and gaseous than where the liquid fuel is drawn intothe engine without mechanical mixing, as where drawn direct from thecarbureter.

In carrying out my invention I provide a rotary fan having aperturedwebs between its blades, which fan is interposed in the passage betweenthe carbureter and the engine intake valve, suitable means beingprovided for rotatively supporting such fan in such passageway. Bypreference I make the fan by pressing the same out of a sheet ofsuitable metal so that the blades and the webs between the blades willbe integral, the openings in such webs being suitably shaped, butpreferably of irregular outline, whereby as the fuel and air are drawnfrom the carbureter by the suction of the engine the fan will beautomatically rotated, and the openings in the webs of the fan will cutup the fueland comminute it in its passage through the fan and at thesame time will thoroughly mix the fuel and air.

By stamping the fan and its webs from a single sheet of metal the fan ismaterially strengthened, while its weight may be relatively light, whichwill be of importance owing to the fact that such fan should be light inweight to freely rotate and not materially resist the flow of air whileat the same time being sufficiently strong to withstand the high speedof rotation to which the fan may be subjected.

My invention comprises novel details of improvement and combinations ofparts that will be more fully hereinafter set forth and then pointed outin the claims.

Reference is to be had to the accompanying drawings forming part hereof,wherein,

Figure l is a plan view of the casing containing my improvements; Fig. 2is a front Specification of Letters latent.

view of the same, partly in section on the line 2, 2, in Fig. 1; Fig. 3is a section substantially on the line 3, 3, in Fig. 1, and Fig. 4 is adetail face View of the fan before it is perforated.

Similar numerals of reference indicate corresponding parts in theseveral views.

At 1 is indicated my improved fan which is provided with openings 1 1 inthe webs between the blades 1. The blades 1 are inclined at a suitableangle with respect to the axis of the fan, and by reference the fan ismade of sheet meta stamped or drawn to the desired shape. By this meansinclined webs or walls 1 are interposed between the blades 1 and thetransversely disposed webs 1 the openings 1 being shown formed in thewebs 1 and the openings 1 formed in the inclined webs 1 By this meansthe fan will rotate by reason of the flow of gas and air while at thesame time such gas and air will pass through the openings 1, 1 and anyliquid fuel drawn to the fan will be comminuted by contact of the partsof the fan surrounding the openings 1*, 1 and thereby also the liquid orgaseous fuel and air drawn through the fan will be thoroughly mixed. Thefan by being stamped from a single piece of material is made relativelystrong and rigid while at the same time relatively light in weight, andas the parts of the perforated fan are thus all integral and unitedwithout seams, danger of breakage of the fan is overcome although thefan may rotate at relatively high speed.

The fan may be mounted upon shaft 8 in any suitable manner within anysuitable casing or passageway. I have shown a suitable casing 3 providedwith threads 3 around the passageway 3 and having an internal shoulder4, and at 5 is a removable cap shown connected with casing 3 by threads6, cap 5 having threads 5 at the passage way 5". The threads 8, 5 permitthe casing to be connected in the line of the piping between thecarbureter and a gas engine. At 7 is an annular shell fitted withincasing 3 and shown bearing at one end against shoulder 4, and providedwith a cross bar or brace 7 serving as a bearing for shaft 8 to whichfan 1 is suitably connected.

At 9 is a cross bar or brace having a bearing adapted to receive shaft8. Said cross bar or brace 9 is shown held in position by its ends beingclamped between the adjacent edge of shell 4 and cap 5. The foregoingprovides a convenient means for removably supporting shaft 8 and fan 1carried by said shaft, and also provides ready means for permittingaccess to the fan for removal, replacement and cleaning of the parts.

My invention is not limited to the particular details of constructionset forth, as the same may be varied, within the scope of the appendedclaims, without departing from the spirit thereof.

Having now described my invention what I claim is 1. A fan provided withblades and webs extending in the spaces between the blades, said websconnecting the edges of adjacent blades, said webs having openings.

2. A fan provided with blades, and having laterally disposed websbetween the blades provided with openings, said webs connecting theadjacent edges of adjacent blades.

3. A fan provided with blades, webs extending from the edges of theblades, said webs being provided with openings, and webs connecting saidfirst named webs with the adjacent blades, the second named webs beingprovided with openings.

1-. A fan made from a single sheet of metal having integral blades andwebs between the blades, said webs connecting the edges of adjacentblades, said webs extending at an angle to said blades and beingprovided with openings.
